IRAN'S deputy foreign minister has said he made proposals to the UN nuclear watchdog chief after pledging "a new approach" to easing international concerns about indications of illicit nuclear bomb research by Tehran.

UN inspectors want to resume an investigation into what it calls the "possible military dimensions" of the Islamic Republic's nuclear programme. Tehran says it is enriching uranium solely for electricity generation and medical treatments.

Hopes of overcoming the stalemate between Iran and the International Atomic Energy Agency over the nature of the nuclear programme have risen since the election of a moderate president committed to easing Tehran's isolation.

Deputy Foreign Minister Abbas Araqchi said he held "very useful" discussions with IAEA Director General Yukiya Amano in Vienna yesterday and had made proposals to him to be addressed in detail by senior IAEA and Iranian experts.

Mr Araqchi said: "I am very hopeful we can come out with a good result."

The talks were the first high-level IAEA-Iranian meeting since Iranian President Hassan Rouhani took office in August, pledging conciliation in the place of confrontation in the Islamic Republic's foreign relations.

Mr Amano said: "It is very important we can show concrete progress."
